Problem with flux

Hello Armando, this is what I found into the handbook "Failure Analysis of Electronic processes" : "...Flux residues with water-soluble flux activators that are conductive and corrosive if left on in large enough quantities are detrimental. If you

Hi All, What are you running for selective solder flux? I'd like any opinion on water soluble and/or no-clean fluxes you are using. In our Kiss 104 machine we use HYDRO-X20 water soluble flux, per the original install suggestion, but I'd like to k

Using a flux pen sounds like a good idea. Comments are: * I assume you�re talking aqueous flux. If not, some NC flux pens leave white residues. Nearly all of 15 samples suffered to varying degrees with white residues. * Use the same flux that you

We use NC flux exclusively for SMT and wave soldering. And it is a fairly old formula from Multicore, though we are currently qualifying a new formula. The automated soldering does not appear to be a problem. It is only the hand soldering that causes

Excellent question. Alloy development is relatively easy compared to flux formulation. New fluxes for Pb-Free alloys need upgrades in 2 critical areas: 1) thermal stability 2) oxygen barrier efficiency Since the Pb-Free alloys require reflow proce
